Relationship between Eurasian large-scale patterns and regional climate variability over the Black and Baltic Seas
Using a NCEP/NCAR Reanalysis dataset and the empirical orthogonal function (EOF) analysis approach we studied interannual to decadal variabilities of the sea-level air pressure (SLP) and the surface air temperature (SAT) fields over Eurasiaduring the 2nd part of the 20th century. Our results agree w...
